SPItING-WHEEL.

,Lyra, in the county of Palo vPinto and State of Texas, have inventedcertain new and useful Improvements in Spring-Wheels, of which thefollowing is .a specification.

This invention relates to improvements in wheels and attachmentstherefor to prevent the wheel from skidding or slipping upon muddy orsoft roads, and has for one of its objects to provide a simplyconstructed device which may be applied Without material structuralchange to wheels of various forms and sizes, and to wheels employedunder various forms of vehicles.

With these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out the claims; and in the drawings illustrative of the preferred embodiment of the inventiom- Figure 1 is a sideelevation of a wheel with the improvement applied; Fig. 2 is a plan viewof the parts shown in Fig. 1; Fig.

3 is an enlargedperspective view of the base portion of the improvedattachment; Fig. 4 is a detached perspective view of one of theanti-slipping-or anti-skidding attachments; Fig. 5- is a transversesection en-- larged, on the line 55 of Fig. 1; Fig. 6 is a perspectiveview of a modified form of one of the creeper attachments; Fig. 7 is anenlarged perspective view, illustrating a modified construction of oneof the antiskidding or anti-slipping attachments.

Corresponding and like parts are referred to in the followingdescription and indicated in all the yiews of the drawings by the samereference characters.

The improved device may be applied without material structural change towheel fellies or rims of various forms, and it is not desiredthereforeto limit the invention to any particular formof wheel or its felly, butfor the purpose of illustration the dc vice is shown applied to a wheelhaving an annuia'r channel shaped rim 1O constructed as illustrated inFig. 5 and with curved resilient spokes 11 united bybolts 12 to the rimand to a hub 13 by bolts 14:.

'ihe anti-skidding attachment comprises a plurality of-segmentai basemembers 15 Specification of Zhetters Patent.

hingedly united at 16 at their confronting ends, the curvature of themembers .15 corresponding to the curvature of the outer face of the rim10 and bearing closely upon the same, as shown in Fig. 1. Any requirednumber of segmental members 15 may be employed, but generally four willbe used, as shown. Preferably, .all but one of the pivot members 16 willbe rivets and one of the members 16 will be in the form of a threadedbolt, so that the united members 15 may be readily attached to ordetached from the folly. I

Each of the members 15 is provided with a plurality of stop lugs 17which bear upon opposite sides of the felly 10, preferably near the endsof the members 15, as shown, and thus eifectually prevent lateraldisplacement of the segmental members. Centrally of each of thesegmental members stop lugs 1.8, spaced apart, are formed and bear uponopposite sides of the fellylO and likewise embrace transverse stop pins19, projecting from the folly member 10. By this means, the unitedsegmental members 15 are effectually prevented from movementcircumferentially of the wheel felly.

Rigidly connected to the outer faces of the segmental members 15 aretransverse ribs 20 spaced at uniform distances apart and preferably eachprovided with studs 21 which extend through suitable apertures,indicated at 22 in Fig. 3, and are riveted to the members 15 from theinner faces thereof. Each of the ribs 20 is provided with a centraloutwardly opening recess, indicated at 23, the recesses thus beingarranged in alinement circumferentially of the wheel. Fitting intl1e,recesses 23 are a plurality of longitudinally directed ribs 24, thelatter being preferably formed in a plurality. of sections with theirconfronting ends in contact, as represented at 25 in Fig. 1. Ifpreferred, the longitudinal ribs 2 1 may be continuous upon the outerfaces of the segmen tal members 15.

By this simple arrangement a non-skidding or non-slipping sheathing orsupplemental rim is produced which may be read ily applied'to wheels ofvarious forms and sizes and to wheels employed for various purposes andwithout the necessity of making material changes in the wheels or theirfollies. someforms of wheels, the trans In 7 a slight modification inthe cone struction is shown consisting in forming each of the transverseribs 20 with out-.

wardly opening recesses 26 at each side of the center and forming therecess 23 in the lower edge of the transverse rib instead of the upperedge, as shown in Fig. 5, and engaging the longitudinally directed rib24 in the recesses'. In the modified structure shown in Fig. 7, the ribZd is of less height than that shown in Fig. i and with a centralprojection 27. These various modifications ,do not constitute adeparture from the principle of the invention as the operation and theresults produced are substantially the same in all. modificationsillustrated.

Having thus described the invention, what is claimed as new is:

1. An attachment for wheels comprising a plurality of segmental supportsadapted to bear around a wheel folly and having stop a lugs near theends bearing upon each edge of the felly and stops spaced apartintermediate the ends, and pins engaging between said spaced stops andadapted to be Copies of'this patent may be inserted in said felly andcoiiperatingwith the spaced stops to prevent the, supports from'movingcircumferentially of the wheel,-

2. In a device of the class described, a plurality of segments adaptedto encompass a wheel, a plurality of grip members spaced apart andsecured to the segments-transversely thereof each of said grip membershaving a recess in its outer'edge, and a plurality of segmental membershaving recesses in their lower edges adapted to coact with the recessesof the grip members. a

3. An attachment for wheels comprising a plurality of segmental membersadapted to bear around a Wheel, an outwardly directed dongitudinal ribbearing upon each of said segmental members, and a plurality of transverse ribs spaced apart and secured to said segmental members andcrossing the longi-' tudinal rib, said ribs having interlocking recesseswhere they cross each other. v In testimony whereof I affix my signaturein presence of two witnesses.
